Online Mitosis Worksheet Answers

1. Which stage does the following occur:
Chromatin condenses into chromosomes: Prophase
Chromosomes align in center of cell. Metaphase
Longest part of the cell cycle. Anaphase
Nuclear envelope breaks down. Pro-metaphase
Cell is cleaved into two new daughter cells. Cytokinesis
Daughter chromosomes arrive at the poles. Telephase
Watch the video carefully.

2. The colored chromosomes represent chromatids. There are two of each color because one is an exact duplicate of the other.

--How many chromosomes are visible at the beginning of mitosis? There are 46 chromosomes at the beginning of mitosis.

-- How many are in each daughter cell at the end of mitosis? 46 are in each daughter cell at the end of mitosis.

--The little green T shaped things on the cell are: They are the centrioles

-- What happens to the centrioles during mitosis? There is one left on each new daughter cell.

3 . Identify the stages of these cells:

a. Metaphase
b. Telophase
c. Interphase

Prophase- In the prophase, the cell's chromosomes condense, its nucleolus disappears, the centrioles travel to the poles, and a web of spindle fiber forms.

Metaphase- During the metaphase, spindle fibers attach themselves to the chromosomes at the kinetochores, and then chromosomes separate into a line along the metaphase plate.

Telophase- Near the end of mitosis, the nuclear envelope materializes again, the chromosomes disperse around the cell, and the spindle fibers dissolve,
